ADJUSTABLE GAGE FOR PLANES.

Specification of Letters Patent. .PatentedJune :1, 1920,

Application filed Ma 19, 1919. serial No. 298,097.

Be it known that I, LAWRENCE C. PAYNE, a citizen of the United States, residing at Anacostia, in the District of Columbia, have invented certain new and useful Improvements in Adjustable Gages for Planes, of which the following is a specification, 7

The inventionrelates to a gage attachment for planes and more particularly to the class of adjustable depth gages for hand planes.

The primary object of the invention is the provision of a gage of this character, wherein the same is mounted inthe body of the plane'and is held normally interior thereof and can be swung without when the occasion requires the use thereof, the gage when exterior of the plane being readily adjustable vertically'so that the depth of cutting action of the plane can be accurately determined with despatch.

Another object of the invention is the provision of a gage attachment of this character, wherein the same can be accurately set at a predetermined distance from the bottom of the plane when the latter is to be used for rabbeting so that an accurate depth 7 of out can be had in theuse of the plane.

A further object of the invention is the provision of a gage of this character wherein the construction thereof is novel in form to assure a uniform depth of cut in the operation of the plane and at the same time any desired depth of cut will be assured.

A still further object of the invention is the provision of a gage of this character which is extremely simple in construction, readily and easily operated, eflicacious in its purpose, and inexpensive to manufacture and install.

Other objects will be in part obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combination and arrangement of elements, the construction being hereinafter fully set forth and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings:

Figure 1 is a side elevation of the plane,

Fig. 2 is a horizontal sectional view taken longitudinally through the body of the plane, showing by full 'linesthe gage "arranged exteriorly of said body and by dotted lines the said gage arranged within the body.

Fig. 3 is a perspective View of the gage removed. Similar references parts throughout the several views in the drawings. I

Referring to the drawing in detail A desigindicate corresponding nates generally the body of the plane, preferably made from metal and is of the hollow type having in one vertical side wall thereof a 'substantially L-shaped slot the lower horizontal portion 5 of which is arranged adjacent to'the bottom of the plane while the vertical portion 6 which is of greaterwi'dth than the horizontal portion extends substantially the depth of thebody A of the plane and through this slot are worked the gage attachment hereinafter fully described. The gage attachment comprises the substantially T-shaped gage 7 the arm portion 8 of which near its free end isformed with a threaded. opening 9 in which is received an adjusting screw 10 correspondingly threaded in the hole 9 and is journaled in the top and bottom of the body A of the plane in proximity to the slotted side walls thereof, the screw 10 being formed with a knurled head 11 at its upper end which is disposed exteriorly of the body 'A of the plane above the top thereof and in this manner the said screw 10 is manually adjusted to raise or lower the gage 7 when swung outwardly through the horizontal portion 5 of the slot in the side wall of the body of the plane with the arm 8 disposed in the the gage to thereby lock the same against accidental adjustment upon the screw 10 and in its adjusted position.

On the outer face of the slotted side wall of the body A of the plane adjacent an edge of the vertical portion 6 of the slot are scale marks 13 with which cooperate the gage 7 j so that the accurate adjustment of the gage can be had and determined at a glance.

Interiorly of the body A of the plane and mounted in 'the' bottom thereof in the path of movement in the gage 7 is a stop 14 which of the plane and can be locked in such position against the stop 14: through the medium of the locking nut 12. Now when it is de-' sired to bring the .gage into use the said gage 7 is'swung'from position interiorly of the body A of the plane through the horizontal portion 5 of the slot to bring the arm 8 into registration with the vertical portion 6 of the slot and on adjustment of the knurled head 11 the said gage 7 can be raised the required height from the plane of the'bottom of the body A of the plane to accurately determine the depth of the cutting action of the said plane when in use in rabbeting a piece of work or when forming a groove therein.

I WVhenf the gagelis swung outwardly of the plane A and hasbeen adjusted the locking nut 12 is turned on the adjusted screw lO to engage with the armi8 of the gage 7 and thereby lock the same in its adjusted position.

' construction and manner of. operation of the thereof, of a gage attachment comprising a From the foregoing it is thought that the thereof, of a gage attachment comprising a swinging gage member movable horizontally through one portion of the slot and adjustable vertically in the other portion thereof, and means mounted in the plane and active upon the gage member for horizontally swinging the same and also vertically adjusting it and means eXteriorly of the plane at the top thereof for themanual manipulation of the adjusting means. V a 3. The combination with a plane having a. substantially L-sh'aped slot in one side wall thereof, of a gage attachment comprising a swinging gage member movable horizontally through one portion of the slot and adjustable vertically'in the other portion thereof, and means mounted in the plane and active upon the gage member for hori zontally swinging the same and alsovertically adjusting it and means exteriorly of the plane at the top thereof for the'manual manipulation of the adjusting means and a stop interiorly of the plane for limiting the inward swinging movement of the gage member.

In testimony whereof I aflix my signature hereto.

LAWRENCE C. PAYNE.
